Too Lean
 

I have recently had my 302 stroked and along with that came several problems i.e map sensor, mass, speed density all that stuff!
Now that I have thoes problems worked out I have noticed that my 347 runs way lean. The valves rattle like mad when I put it under a load and it starts to cut out. I had it check out and the result was lean. I have been told that the injectors need to be upgraded and I don't know **** about Injectors. I have a 1990, 302/347 any Help or hints?
Thank you

At least you should go with a set of 30lb injectors for that combo, don't forget to change the mass air also to match the injectors.

Ok, I understand this
So today I called summit and ask the to tell me what type/brand injectors I need to put with this Mass air sensor that I purchased from them one year ago to solve this problem. Now I find out that they sold me one that is calibrated to 19lb injectors and I would need a new one, plus injectors. Do ya see what i'm saying! Why would their tech guy not tell me this from the start. He new I had a stroked engine would he not be far elong enough in his training as the "tech" or is this just selling more parts thing.
